Scrap the pie charts. It's a lot easier to see the difference between 50 and 55% when it's represented as the coloured part of a column representing 100% Pie charts only work when the difference are big enough.

I probably would not even make a map of the data in the first place. I would just have a bar chart like you drew, because the amount of data is so low, and their geographical position does not offer much additional information or context.
Funnily enough, I am actually taking a cartography class at uni right now, and a map (on the left) almost like this is in our textbook. The author then showed a redesign (on the right) where he uses columns for representing the statistics as bars instead of numbers.
I'm aware it's not an exact 1-1 example, but I think you'll agree that the one on the right is more successful in communicating the differences between states (which I am assuming is the purpose OP's map as well). This book is as far as I know peer-reviewed and the most authoritative guide on map design in Denmark at least. The author Lars Brodersen is well-respected in his field. According to him, there are certain guidelines when it comes to visual design, that make for better, more useful maps.
